class_docstr: Wraps env configurations to include extra rllib metadata.
  
  These attributes can be used to parameterize environments per process.
  For example, one might use `worker_index` to control which data file an
  environment reads in on initialization.
  
  RLlib auto-sets these attributes when constructing registered envs.
